MOS Versions

[Pernod]

MAME currently supports MOS versions 1.2 and 1.21 for the TC-01, and 2.1 for the 256.

I believe there are other versions out there, specifically a 1.1 and maybe 1.0. Could owners check which version their machines have installed, and provide a ROM dump of any not already dumped. Thanks.

I'll check my TC-01 ASAP; but I doubt that I find anything special...

1.2 in mine.

I’m not sure my MOS ROM has a number on it. Any other way to find out?

Yep, it's right there on the screen.

I'd be especially interested as I would probably have to make changes to the einSDein ROM. I've never encountered anything less than 1.2, I always ask what the rom version is.
